Specification of Letters Patent.

Patented Jan. 14, 1913.

Application filed June 28, 1912. Serial No. 706,480.

To all whom it may concern Be it known that I, PAUL CRAMER, a citizen ofFrance, residing at Berck- Plage, Pas de Calais, France, have inventednew and useful Improvements in Air and Gas Regulators, of which thefollowing is a specification.

This invention relates to air and gas regulators for incandescent orBunsen burners and the principal object of the invention is to provide asimple and efficient device, which by the simple movement of the lever,properly regulates the entrance of air in accordance or in the properproportion with the gas fed so that a maximum amount of heat orillumination may be obtained with a minimum use of gas.

Further objects of this invention will appear as the following specificdescription is read in connection with the accompanying drawing, whichforms a part of this application, and in which Figure 1 is a sideelevation. Fig. 2 is a similar view taken from the opposite side andwith the lever in its opposite position. Fig. 8 is an elevation similarto Fig. 1 with the air regulating sleeve removed. Fig. 4 is a verticalsectional view. Fig. 5 is an elevation of the air regulating sleeveremoved. Fig. 6 is a detailed side elevation partly in section showing amodified form.

Referring more particularly to the drawing, 1 represents an ordinary gassupply pipe to which is secured a gas feeding tube 2 having a flangedhead 3 with" the exterior portion thereof threaded on one side of theflange, as shown at 4:, to receive a mixing tube 5. The tube 2 isprovided in its center portion with a needle point 6 and on oppositesides of the needle point with feed slots 7 through which the gaspasses. This tube is also externally threaded and mounted thereon is avalve body 8 which is provided with a central aperture in its end, asshown at 9, adapted to be entered and closed by the needle point 6. Thisvalve body is provided with a packing gland 10 and has its movementscontrolled upon the threaded stem of the tube 2 by means of an operatingrod 11 having a button 12 on its outer end. This rod or pin 11 projectsthrough a slot 11 in the mixing tube 5, the slot being preferably of awidth equalling the diameter of the rod and being formed with a pitchcorresponding to the pitch of the threads on the tube 2. The rod '11also passes through a vertical slot 13 formed in the air regulatingsleeve 14; which, as shown, is provided with a diagonal slot 15 engagedby a pin 16 threaded into the mixing tube 5. The mixing tube, as shown,is provided with a plurality of openings 17 which are controlled by themovements of the sleeve on the mixing tube. When the lever is moved inone direction or toward the right, as shown in Fig. 1, the valve bodywill be turned upon the tube 2 so as to cause the needle point to enterand close the aperture 9. Simultaneously with this action, the airregulating sleeve is rotated by the rod 1] engaging one of the walls ofthe vertical aperture 13 and the same moved downwardly over the mixingtube to close the apertures 17 therein by reason of the fact that onewall of the slot 15 is engaged by the pin 16. This moved, as beforestated, simultaneously cuts off the gas and air and the oppositemovement opens the valve and also the air ports in proportion to theflow of gas. In this manner, the maximum amount of air is used inproportion to the flow of gas.

In the modification shown in Fig. 6, the mixing tube 5 is provided withan enlarged openin 20 which is adapted to admit air to the mixing tube.This opening is controlled by asleeve 21 horizontally movable on themixing tube by means of an operating button or pin 22 which is engagedwith the valve 8, as is usual, and passes through an aperture in thesleeve 21. The sleeve is held in its horizontal position by a pin 23which is secured to the mixing tube and passes through a slot 24 in thesleeve 21. The sleeve 21 is provided with a tapering aperture 25 whichoperates over the aperture 20 and regulates the amount of air suppliedto the mixing tube and covering this slot is a shield 26 which preventsdirect inflow of the air.

What is claimed is A regulator for incandescent burners comprising amixing tube having apertures therein, a tubular head connected to thesame and adapted to be connected to a source of fuel supply, anapertured valve body threaded upon said tubular head Withciprocate overthe apertures in the mixing in the mixing tube, a needle carried by thetube when the same is rotated thereon. 10 tubular head for closing theaperture in the In testimony whereof I afiix my signature valve body,means for rotating the valve in presence of two Witnesses.
